X-linked osteoporosis with fractures

X-linked osteoporosis with fractures is a rare, genetic, primary bone dysplasia with decreased bone density disorder characterized by childhood-onset osteoporosis associated with recurrent, multiple, osteoporotic, long bone fractures and/or vertebral compression fractures, significant height loss in adulthood, low bone mineral density scores, and otherwise no other abnormalities. Heterozygote females may be unaffected or have a milder phenotype.
